This is actually kinda funny and even fresh for me. These two really are not in love with each other. They dont got that "Ahn nononon me no likey but ahhhnnn" bullcrap. They probably will fall in love but the fact that they both are not even after the assassination make this the most logical romance in manhwa history. U dont go stranger to lovers within 3 chapters. You gotta reach familiar and comfortable first before mating interest.
